Title: Method for manufacturing a workpiece by friction welding to reduce the occurence of abnormal grain growth
Inventor: LEDERICH RICHARD J
IPC: B23K20/12
Filed: 2008-03-14
Abstract: A method of manufacturing a workpiece is provided. The method generally includes friction stir welding at least one structural member, selectively-removing material (48, 50) from the surfaces (38, 40) of the workpiece at the location of a friction stir weld joint (20), and thereafter subjecting the workpiece to a solution treat, quench, and age treatment. By selectively removing regions from the surfaces of the workpiece that are defined by nonuniform material properties adapted to nucleate nonuniform grain growth during' the solution treat, quench, and age treatment, a subsequent grain growth during the thermal treatment can be at least partially prevented.

Filed: 2009-12-14
Abstract: Prepregs for manufacturing composite materials comprise of fibrous material contacting polymerisable resin, wherein at least 50 wt% of the resin comprises at least one polymerisable monomer having at least two carbon-carbon unsaturated functional groups. A preferred example of the polymerisable monomer is a polyvinylester, the vinyl group comprising a (meth)acrylate group and the polyester including an epoxy resin residue. The monomer is polymerisable by reaction of the unsaturated functional groups to form a cured resin preferably wherein the heat of polymerisation is less than 230 KJ/kg to provide maximum increase in temperature of the prepreg of 60°C during polymerisation under adiabatic conditions. Also disclosed is a method of producing the prepreg. Further disclosed is a prepreg comprising a fibrous material impregnated with a radical curable, polymerisable polyfunctional unsaturated resin, the resin comprising at least one polymerisable monomer, at least 50 wt% of the monomer having a general formula An-B, wherein A is an unsaturated functional group derived from a hydroxyalkyl ester of (meth)acrylic acid with a dicarboxyl acid or acid anhydride and B is a functional group derived from a multifunctional epoxide having n epoxide groups where n is at least 2. Further disclosed is a prepreg comprising fibrous material impregnated with a radical curable, polymerisable polyfunctional unsaturated resin, the resin comprising at least one polymerisable monomer, at least 50 wt% of the monomer having a general formula Cm-D, wherein C is an unsaturated functional group derived from a glycidyl (meth)acrylate and D is a multifunctional compound with m reactive sites, each site capable of reacting with an epoxide group and is derived from a carboxylic acid, a phenol or at least one of a primary alpine or a disecondary amine, m is at least 2. Also disclosed is a method producing a moulded fibre-reinforced composite material comprising polymerising the monomer in the prepregs to form a cured resin matrix containing the fibrous material.

Title: Improvements in and relating to methods of presenting stereoscopic pictures
IPC: G02B30/32
Filed: 1938-04-01
Abstract: 514,426. Stereoscopic photographs. DUDLEY, L P. April 1, 1938, No. 10061. [Classes 97 (i) and 98 (ii)] In. order that a parallax stereogram shall present a stereoscopic effect independently of the point of view, some of the-vertical left and right eye strip elements of-the stereogram, or a portions of these elements, are displaced laterally with respect to the remainder, and a normal viewing screen'with vertical spaced lines is employed, so that over a wide angle of view a partly stereoscopic and partly pseudoscopic effect is obtained. The former effect predominates, and is sufficient to give a correct three-dimensional appearance'. Alternatively, a normal stereogram may be used in conjunction with a screen in which some, or parts of the vertical lines are displaced laterally. Fig. 6, shows one form of stereogram in which the normal right and left eye vertical strip picture elements r, l have been shifted laterally through the width of one element in alternate horizontal bands, so that portions 'of each element will be seen by the correct eye when viewed from any normal position through a screen of vertical lines. Fig. 8 shows one form of grid for viewing a normal stereogram in which half the lines have been moved laterally 'through a distance equal to the width of one space, and Fig. 10, shows another form divided by a curved boundary into upper and lower areas, the lines in each of which are a prolongation of the spaces in the other. The modified stereograms may be produced by taking them or projecting them through a suitably modified screen, and may be used in conjunction with a kinematograph camera or with television transmitters or receivers.

Abstract: 470,657. Refrigerating. ELECTROLUX, Ltd. (Shagaloff, H. C.) April 6, 1936, No. 10109. [A Specification was laid open to inspection under Sect. 91 of the Acts, Oct. 12, 1936.] [Class 29] Absorption systems.-In continuous-cycle equalized-pressure systems employing a soluble and an insoluble refrigerant, e.g. ammonia and propane, inert with respect to one another, the insoluble propane vapour is condensed in the upper part of the absorber 21 and the condensate is separated by gravity from the solution in the absorber and fed back to the upper part of the evaporator 13 through a U-seal 31. The strong solution passes through a heat-interchanger 34 and " pump " coil 39 to a generator 10 of usual form, and the ammonia generated therefrom is condensed at 15 and led through a seal 19 to the top of the evaporator. The vapour mixture from the evaporator enters the lower part of the absorber, down which the weak solution flows over upper and lower series of baffle plates 22, 29. The upper part of the absorber is cooled by a water coil 23 and the propane condensed therein flows with the ammonia solution into the wide longer leg 25 of a U- tube separator, The propane floats off through the seal 31 and the solution overflows the shorter limb 26 and absorbs further ammonia before flowing back to the generator.

Title: Improvements in or relating to process and oven for low temperature carbonisation inretorts
IPC: C10B1/04
Filed: 1934-04-04
Abstract: 436,373. Carbonising-apparatus. INTERTRUST COMPAGNIE GENERALE DE DISTILLATION ET COKEFACTION A BASSE TEMPERATURE ET MINIERE SOC. ANON., 1, Post Strasse, Glaris, Switzerland.-(Assignees of International Holding de Distillation et Cokefaction a Basse Temperature et MiniÞre (Holcobami) Soc. Anon. ; 8, Rue de la Rigence, Brussels) April 4, 1934, No. 10249. Convention date, April 4, 1933. [Classes 51 (i), 51 (ii), and 55 (i)] In a low temperature carbonizing plant in which the heating-gases are recirculated through the retort chambers, the outgoing gases, before entering and after leaving an external circuit including a fan or other impeller, are passed through a heat exchanger which in effect short circuits the external path taken by the gases, and the returned gases, together with the necessary quantity of fresh combustion gases, are then distributed uniformly over the cross section of the retort chamber. In the vertical retort plant shown the waste gases leave the retort chamber through the port 11, pass downwards through the tubes 12 of the heat exchanger 4 into a header 14 common to all the settings of a battery, and are returned by the fan 15 through a second header 16 and the space around the tubes of the heat exchanger. The returned gases enter the combustion chamber 5 through a forked flue 7 to mix with fresh gases from the burner 6, and the flow of the mixture is subdivided and constricted by the retorts and baffles 8, 9, 10 so that the gases are evenly distributed in the retort chamber. A byepass 19 is provided between the ends of the headers 14, 16 remote from the fan, and is controlled by a valve 20 automatically operated in accordance with the pressure in the header 14. A similarly-operated valve in connection with the header 16 controls the escape of surplus gases from the system. The two headers are made larger than is necessary to accommodate the flow of gases in the circuit so that they will act as a reservoir to compensate for variations in the volume of gases in circuit. Discharging.-The retorts have perforated inserts 24 which are suspended from the top of the setting, and are lowered to allow the discharge of the coke. The inserts are supported at their lower ends on a closure member 25, in which is formed a duct for the supply of water or steam for cooling the coke before discharge. After the coke has been cooled the closure 25 is lowered by a ram 32 and moved to one side and the inserts are then lowered on separate rams 34 to allow the coke to fall into the shoot 35. The heating of the retorts is preferably maintained during the charging and discharging operations.
